The document summarizes an HDMI active optical cable (AOC) called the Zeta Link. It can transmit high-definition audio and video signals from devices like set-top boxes, DVD/Blu-ray players, and game consoles to displays over distances up to 328 feet. The cable uses plastic optical fibers that are thinner, lighter, and more flexible than copper cables. It provides highly stable signal transmission even in noisy environments since it is not susceptible to electromagnetic or radio frequency interference. Key features include support for 4K resolution, 3D, and HDMI 2.0 technologies over its long transmission length without signal loss.
